该文通过在C^n中的有界星形圆型域和复Banach空间中的单位球上建立一些偏微分不等式,分别给出α次的殆星映射在这两类域上的充分判别条件。
In this paper, the authors establish some partial differential inequalities on bounded starlike circular domains and the unit ball of Banach norm in C^n. Then using these inequalities, the authors get two suifficient conditions for almost starlike mappings of order α.
